This 2 pack of motion activated lights is great for the front of my house. I like to have the lights for security reasons, as there have been many burglaries in my area lately. It is nice to have lights that come on when we get out of our cars at night and need to see where we're going. The bulbs fit in standard light sockets so there is no need for any special adapters. Each light bulb has a sensor on the end to detect motion that detects at 120 degrees at 16 feet. They are LEDs so they are energy savers, also they only use 7 watts of power. The lights stay on for 40 seconds after being activated. Get yours at https://goo.gl/hkwrX3. #RankBoosterReview #Sponsored #Vgogfly #security #motionlights #LED #f4f
